如果选择真正改变onItemSelectedListener才触发？ [英] onItemSelectedListener only triggered if selection actually change?

问题描述

我用 setOnItemSelectedListener 上一个微调。
如果我改变选择的侦听器被触发，但不是如果我选择已选中相同的项目。
我需要nofified即使用户选择已选择了相同的项目。
我因子评分关于使用 setOnItemClickListener ，但它不是由微调。

I use setOnItemSelectedListener on a spinner. The listener is triggered if I change the selection but not if I select the same item that is already selected. I need to be nofified even if the user select the same item that is already selected. I tought about using setOnItemClickListener but it is not supported by the Spinner.

任何提示？

TIA
